The men were hurt at Orchard Beach on Pelham Bay in the Bronx at about 5 p.m., and were being treated at Jacobi Medical Center, according to the FDNY. They did not appear to be seriously injured or physically burned.

Telemundo identifies two of the victims as a father and son, 49 and 19 years old, who sought shelter under a tree during the storm. A friend of the family told the news station that the lightning hit the tree, then sent the men flying at least 10 feet.

The friend showed the station photos of the victims' clothing that appeared to be shredded in parts from the lightning strike.

Visitors at Orchard Beach said they weren't seriously concerned about the rain until they heard the thunder.

"That crack of thunder and lightning came, and that's when everybody started to run away," said Cheryl Greenidge.

Edgar Ayalla said he saw lightning hit either the beach or the water "like an explosion," and that debris was sent flying from that lightning strike.
